Paper-based electronics have arrived. Well, they’re already here. But the use of paper electronics is set explode thanks to rapid advancements in 2D printing.
Paper-based electronics have primarily been limited to use in printed organic electronics. While this is promising for commodity applications such as packaging tags and toys, the speed of organic semiconductors is not suitable for most radio-frequency applications. Among the uses for which paper-based electronic devices have been heretofore unsuitable is connecting to the cloud over Bluetooth frequencies for the Internet of Things (IoT), smart sensors, and other smart applications.
Researchers at the University of Texas at Austin (UT-Austin) are reporting this week at the International Electron Devices Meeting that graphene and molybdenum disulfide (MoS2), with their extraordinary conductivity, can enable paper-based electronics to achieve the frequency required to make them fit for IoT and smart sensor applications. The researchers claim that this work represents the first time that high-performance two-dimensional (2D) transistors have been demonstrated on a paper substrate.
Despite the fact that paper has been shown to be applicable to printed organic electronics in the past, it has not traditionally been manufactured with electronics in mind. As a result, regular sheet of office paper is not well suited to high-performance transistor manufacturing.
